Substitute Part Grouping Explanation

Substitute parts for the RC5025F274CS are qualified based on the following substitution criteria:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package type: 2010 (5025 Metric) (exact match required for PCB compatibility)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts must meet or exceed 0.667W minimum rating. Higher power ratings are acceptable as they provide equal or superior thermal performance without affecting circuit functionality.
• Physical dimensions and height: Minor variations within supplier specifications are acceptable provided the 2010 package footprint is maintained.

The RC2010FK-07270KL from YAGEO qualifies as a direct substitute based on these criteria, with the distinction of a higher power rating (0.75W vs. 0.667W), which represents an upgrade in thermal capability.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-07270KL from YAGEO is a qualified substitute for the RC5025F274CS from Samsung Electro-Mechanics. Both components maintain Active product status and full compliance with ROHS3 and REACH regulatory requirements. The substitute part provides identical electrical performance across all critical parameters: resistance value, tolerance, temperature coefficient, and operating temperature range. The increased power rating (0.75W vs. 0.667W) represents a thermal margin improvement without introducing any compatibility issues. Physical dimensions and package footprint are functionally equivalent, ensuring direct PCB layout compatibility. Both components carry MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these parts may be based on availability, lead time, pricing, or supplier preference, as electrical and mechanical performance are equivalent within the specified design envelope.

Frequently Asked Questions (FAQ)

Q: Can the RC2010FK-07270KL be used as a direct replacement for the RC5025F274CS on existing PCBs?

A: Yes. Both components share identical package dimensions (2010/5025 Metric), footprint, and physical height specifications. Direct PCB substitution is supported without layout modifications.

Q: What is the significance of the higher power rating on the substitute part?

A: The RC2010FK-07270KL is rated at 0.75W compared to the RC5025F274CS at 0.667W. This represents a 12.5% increase in power dissipation capability. In circuit applications, the substitute part provides additional thermal margin and will operate at lower junction temperatures under identical load conditions, potentially extending component life.

Q: Are there any differences in temperature stability between these parts?

A: No. Both components specify an identical temperature coefficient of ±100ppm/°C and operate across the same temperature range (-55°C to 155°C). Resistance drift characteristics are equivalent.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the RC5025F274CS and RC2010FK-07270KL are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 moisture sensitivity ratings. Regulatory compliance is identical.

Q: What packaging formats are available for the substitute part?

A: The RC2010FK-07270KL is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any tolerance or precision differences between these resistors?

A: No. Both components maintain ±1% tolerance specifications. Precision and accuracy are equivalent for circuit design purposes.
